Carnation plant named ‘Yoder Ice’

ABSTRACT

A distinct cultivar of Carnation plant named ‘Yoder Ice’, characterized by its large white-colored flowers; strong flowering stems; strong calyxes that resist splitting; good postproduction longevity with flowers maintaining a good substance and color for about ten days in an interior environment after shipping; and resistance to  Fusarium oxysporum .

Botanical designation: Dianthus caryophyllus.

Cultivar denomination: ‘Yoder Ice’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Carnation plant, botanically known as Dianthus caryophyllus and hereinafter referred to by the name ‘Yoder Ice’.

The new Carnation is a product of a planned breeding program conducted by the Inventor in Salinas, Calif., and Madrid, Cundinamarca, Colombia, South America. The objective of the breeding program is to create new cut Carnation cultivars having long flowering stems, early flowering, attractive flower color and good flower form and substance.

The new Carnation originated from a cross-pollination made by the Inventor in 1998, in Salinas, Calif., of a proprietary selection of Carnation identified as code number 0528, not patented, as the female, or seed, parent, with a proprietary selection of Carnation identified as code number 0732, not patented, as the male, or pollen, parent.

The cultivar Yoder Ice was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Madrid, Cundinamarca, Colombia, South America in March, 2000. The selection of this plant was based on its flower color and good flower form and substance.

Asexual reproduction of the new Carnation by terminal cuttings in Madrid, Cundinamarca, Colombia, South America since April, 2000, has shown that the unique features of this new Carnation are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Yoder Ice has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Yoder Ice’. These characteristics in combination distinguish ‘Yoder Ice’ as a new and distinct cultivar of Carnation:

-   -   1. Large white-colored flowers.     -   2. Strong flowering stems.     -   3. Strong calyxes that resist splitting.     -   4. Good postproduction longevity with flowers maintaining good         substance and color for about ten days in an interior         environment after shipping.     -   5. Resistant to Fusarium oxysporum.

Plants of the new Carnation can be compared to plants of the female parent selection. In side-by-side comparisons conducted in Madrid, Cundinamarca, Colombia, South America, plants of the new Carnation and female parent selection differed in the following characteristics:

-   -   1. Flowers of plants of the new Carnation were about 1 cm larger         than plants of the female parent selection.     -   2. Plants of the new Carnation flowered about two weeks later         than plants of the female parent selection.     -   3. Plants of the new Carnation and the female parent selection         differed in flower color as plants of the female parent         selection had light pink-colored flowers.

Plants of the new Carnation can be compared to plants of the male parent selection. In side-by-side comparisons conducted in Madrid, Cundinamarca, Colombia, South America, plants of the new Carnation and the male parent selection differed in the following characteristics:

-   -   1. Plants of the new Carnation were about 18 to 20 cm taller         than plants of the male parent selection.     -   2. Plants of the new Carnation flowered about three weeks later         than plants of the male parent selection.

Plants of the new Carnation can also be compared to plants of the cultivar Kali, not patented. In side-by-side comparisons conducted in Madrid, Cundinamarca, Colombia, South America, plants of the new Carnation and the cultivar Kali differed in the following characteristics:

-   -   1. Plants of the new Carnation were taller than plants of the         cultivar Kali.     -   2. Plants of the new Carnation flowered about two weeks later         than plants of the cultivar Kali.     -   3. Plants of the new Carnation and the cultivar Kali differed         slightly in flower color as plants of the cultivar Kali had         light creamy white-colored flowers.     -   4. Plants of the new Carnation were resistant to Fusarium         oxysporum whereas plants of the cultivar Kali were very         susceptible to Fusarium oxysporum.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. The following observations and measurements describe plants grown in Madrid, Cundinamarca, Colombia, South America under conditions which approximate commercial practice in a single-layer polyethylene-covered greenhouse. Four-week old rooted cuttings were planted in ground beds and pinched about three to four weeks later. During the production time, day temperatures ranged from 19° C. to 24° C.; night temperatures ranged from 4° C. to 12° C.; and light levels ranged from 3,000 to 5,000 foot-candles. Measurements and numerical values represent averages for six to ten typical flowering stems about 27 weeks after planting.
